  checks exports itself.
  This is a content change.

 file system, a very limited set of operations are permitted, so that an
 NFSv4 client can traverse the tree to an exported file system.
 Although parts of the NFSv4 tree can be non-exported, the entire NFSv4 tree
 must consist of local file systems capable of being exported via NFS.

 NFSv4 does not use the mount protocol and does permit clients to cross server
 mount point boundaries, although not all clients are capable of crossing the
 mount points.
